Horizontal wheel scrolling and gyroscope-based orientation feel inverted

[aaugustin]

I'm using Reel to display a view of an objects with 24 frames.

I set cw: true because my frames appear to be inverted compared to what Reel expects.

At this point:

• dragging is intuitive: the side of the object that's closest to me follows the dragging direction
• horizontal wheel scrolling feels inverted: the side of the object that's closest to me goes in the opposite direction of scrolling (I tested this with Windows users to make sure I wasn't simply a victim of Apple's scrolling convention — they swapped vertical scrolling a few years ago)
• gyroscope-based orientation feels inverted: instead of "rotating around the object", which would be the natural behavior, the object appears to rotate twice as fast as the mobile device

If I leave the default of cw: false, scrolling and orientation feel natural but dragging feels inverted.

Is this an intentional design decision or a bug?

Is there a way to swap only the direction of dragging, not of other interactions?

There's probably two distinct issues here.

1. Gyroscope orientation.

The panorama-orientable-stitched example is obviously correct. But if you take one of the "object" examples and add the "orientable" feature, it should feel incorrect (assuming your brain visualizes space like mine).

I believe that the proper direction depends on whether the user is "inside" the picture (in the case of a panorama) or "outside" the picture (in the case of an object). As a consequence, I suggest to provide an option to swap just the direction of gyroscope orientation when orientable is enabled.

1. Horizontal scolling.

There are no examples in your gallery which I could use to illustrate my point.

The general idea is that "dragging left-to-right" and "scrolling left-to-right" are similar gestures and should have the same effect. Currently they have opposite effects. I think it's a bug and it should be fixed; it doesn't need an option.
